The D90 USB input does not appear to be isolated, so the SU6 brings the advantage of better isolation from RF noise coming from the host.Another question I have topping d90 dac which is already with two accusilicon as318b how is ddc going to do better except I can use i2s connection
Isn't accusilion better than crystek cchd-957
I mean how does it help the clock to do better using external vs on board dac
Check the user manual to see if the D90 allows you to select the clock source that is I2S clock (CCHD957) vs the internal clock (AS318)
The 2 crystals are pretty close in performance, all things being equal, I would choose the internal source as it is physically much closer to the DAC chip and subject to less effects from signal propagation delay.
